Thyroid No Surgery for Benign Nodules 101: Mutation studies prevent 70% from going to surgery with an indeterminate biopsy diagnosis when the FNA needle washout mutation markers and classifiers are benign.
A consultation with an expert in DNA/microRNA testing to repeat the biopsy with collection of molecular marker should be routine before your physician refers you for a major thyroid surgery with multiple complications and pain and suffering post op.
Refuse surgery until you have all the facts to make the correct decision.
Remember thyroid surgery for nodules is never an emergency and is always elective and can be postponed for up to 6 months giving you time to get a expert second opinion.
Dr.Guttler’s thyroid center was one of 9 used in this important study designed and proven to decrease and opt out of surgery with negative markers, and opt in to have surgery when they are positive.
Interpace Diagnostics Presents Favorable New Data at the 88th Annual Meeting of the American Thyroid Association (ATA)
ThyGenX® and ThyraMIR® Data from Clinical Experience Study Shows Positive Results
PARSIPPANY, NJ, Oct. 15, 2018 (GLOBE NEWSWIRE) — Interpace Diagnostics Group, Inc. (NASDAQ: IDXG) announced that the Company presented new data at the 88th Annual Meeting of the American Thyroid Association (ATA) on Friday, October 5th supporting its molecular tests for thyroid cancer. The new interim data spanning over 300 samples from a two-year, “real world,” retrospective study highlighted the clinical utility of Interpace’s ThyGenX® thyroid oncogene panel in combination with its micro-RNA classifier, ThyraMIR®. J. Woody Sistrunk, MD, founder of the Jackson Endocrine and Thyroid Clinic in Jackson, MS, presented the results during a live poster session and as part of the Product Expo Theater presentation. Currently, the data submission process for publication is underway and the complete results will be made available at that time.
Nine centers from across the U.S. participated in this study, including Dr. Sistrunk’s clinic, and the data demonstrated that ThyGenX®/ThyraMIR® combination test results help avoid unnecessary surgical resections and identify nodules where surgery is appropriate in cytologically indeterminate thyroid nodules. Importantly, the study also demonstrated that surgical decisions made based on the combination test results were appropriately aligned with risk of malignancy over clinical follow-up consistent with a combination test that effectively rules-in and rules-out higher risk of malignancy. These results further confirm the value added by ThyGenX®/ThyraMIR® combination testing in the risk stratification of thyroid nodules when confronted with an indeterminate cytology diagnosis. These findings are aligned with data from the tests’ original validation study conducted by Labourier et al., which was published in the Journal of Clinical Endocrinology and Metabolism (JCEM) in 2015.
The Company also found that the cancer rate among patients who underwent molecular testing was often much lower when compared to the rate of cancer typically reported for other molecular products. Accordingly, the data showed that a combination test which both rules-in and rules-out cancer is more clinically useful given the rule-in feature found in the ThyGenX®/ThyraMIR® combination test helps to single out those patients who exhibit a higher risk of cancer from the majority who do not.
Recently, Interpace launched an expanded mutation panel called ThyGeNEXT™, which includes additional markers such as TERT, PTEN, ALK, and RET among others. As the Company’s Clinical Experience Study progresses, patients tested with ThyGeNEXT™ will also be included to demonstrate the clinical utility of the latest version of the product.
About Thyroid Nodules and ThyGeNEXT Testing
According to the American Thyroid Association, approximately 15% to 30% of the 525,000 thyroid fine needle aspirations (FNAs) performed on an annual basis in the U.S. are indeterminate based on standard cytological evaluation, and thus are candidates for ThyGeNEXT™ testing. ThyGeNEXT™ provides high predictive value in determining the presence of cancer in thyroid nodules. The test can improve risk stratification and surgical decision-making when standard cytopathology does not provide a clear diagnosis for the presence of cancer. ThyGeNEXT™ is covered by both Medicare and most Commercial insurers.
Like ThyGenX®, ThyGeNEXT™ utilizes state-of-the-art next-generation sequencing (NGS) to identify more than 150 genetic alterations associated with all forms of thyroid cancer, including papillary, medullary and follicular thyroid carcinomas. According to the American Cancer Society, thyroid cancer is the most rapidly increasing cancer in the U.S., with rates tripling in the last three decades.
Most physicians have traditionally recommended thyroid surgery where thyroid nodule biopsy results are indeterminate, not clearly benign, or malignant following traditional cytopathology review; however, without the use of molecular testing, over 70% of these surgical procedures have been found to be ultimately unnecessary, with the nodules being benign.
Molecular testing using ThyGenX® has historically been shown to reduce the rate of unnecessary surgeries in indeterminate cases. To date, the Company has performed ThyGenX® and ThyraMIR® testing on over 25,000 patients and will continue to collect cases into the thyroid registry, which will provide the basis of a peer-reviewed publication confirming the impact of ThyGenX® and ThyraMIR® on physicians’ treatment decisions in real-world settings. The Company will continue to collect data adding to the thyroid registry in order to report utility of the expanded mutation panel, ThyGeNEXT™, over time.
